Benefits of technology

The present invention relates to a method and computer for detecting the level of drowsiness of a vehicle driver. The method involves analyzing the driver's behavior and determining quantitative parameters that represent their level of attention. When the driver's level of drowsiness is higher than a predetermined threshold, the method warns the driver to maintain awareness. The computer programmable logic device performs the monitoring phase and provides real-time information to the driver. The parallel implementation of the algorithm covers the majority of event possibilities and can provide the best warning in real time for the driver. The technical effects of the invention are a simple, reliable, and effective solution for detecting driver drowsiness and alerting the driver to maintain awareness for safe driving.

Problems solved by technology

Consequently, the device may trigger warnings, which presents an appreciable drawback, or conversely not trigger a warning even though the driver is in a distracted or drowsy state, which then presents a major drawback.

Embodiment Construction

[0049]The computer according to an aspect of the invention is intended to be mounted in a vehicle, in particular a motor vehicle, which may be manually driven or self-driving, in order to determine a level of drowsiness of the driver of said vehicle and to warn them or activate automatic driving if necessary. The level of drowsiness may correspond to a state (asleep, unconcentrated, alert, etc.) or a level which is quantized, for example alphanumerically, in order to define levels representing grades of drowsiness (for example, level 1 for an alert driver, level 2 for an unconcentrated driver, level 3 for a driver falling asleep, level 4 for a sleeping driver, etc.).

[0050]With reference to FIG. 1, the device comprises a camera 11 installed in the vehicle 1, which films the driver, and a computer 12, also on board the vehicle 1, which processes the images generated by the camera 11.

[0051]The camera 11 is, for example, placed behind the driver's steering wheel and makes it possible to...

Abstract

A method for determining a level of drowsiness of a driver of a motor vehicle on the basis of a predetermined image analysis algorithm, the vehicle including a camera and a computer, the computer implementing the predetermined algorithm on the basis of a set comprising at least one parameter relating to the attitude of the driver, the method, implemented by the computer, including a phase of learning and a phase of monitoring the state of the driver.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the U.S. National Phase Application of PCT International Application No. PCT / EP2019 / 085147, filed Dec. 13, 2019, which claims priority to French Patent Application No. 1872824, filed Dec. 13, 2018, the contents of such applications being incorporated by reference herein.FIELD OF THE INVENTION[0002]The invention relates to the field of assistance in the, and relates more particularly to a device and a method for driving of a motor vehicle, whether manually driven or self-driving monitoring a vehicle driver in order in particular to trigger a warning or activate an automatic driving mode in the event of drowsiness or distraction.BACKGROUND OF THE INVENTION[0003]Nowadays, it is known practice to equip certain motor vehicles with a monitoring device that allows the driver to be alerted if they appear distracted or if they are sinking into a state of drowsiness. This type of monitoring device comprises a camera and a comput...
